MPROV ED SUGAR-MOULDS.

T0 ALL WHOM IT MAY CONCERN:

Be i: known t hat I, JOIIN S. INSKEEP, of West Middleburg, Logan county, State of Ohio, havo invented a new and improved Suga.r-Mould; and I do hereby declare the following desription end acoompanyfmg drawings are sufiicent to enable any person sklled in the art; or science to which il; most nearlv appertan's to make and use my soid invention, or improvements witbout further invention or experimen t.

The nature of my in vention and improvemont consists in constructing a, mould for forming blocks or cakes of maple, sorghum, anrl other sugzns, by providing a, frame or box, Without bottom, of wood or other suitable materia], end squame, oblong, or polygonnl in shape, and then cutting a,nd bending a. pieoe of tin or other sbeet metal so as to forni a. complete box, just fitting into tbe frame aforesaid, bui: with the sides and 'ends Ioose or detached from each other, being held in pace by the frame to receve che liquid sirup, but readily springing ofi whenit; has coolod and become solid, and the box is removed from the frame, thus releasing at once the cake formed, the bottom of the box beibg support-ecl free from contaot \yith any surf'ace, so as to allow a. free circulation of air beneatb, to hasten the cooling and hardening of tbe sirup.

In describing my improved mould, I refer to :be aocompanyng drawings, forming part; of ths speoificzti0n- Figure 1 being an elovation of the frame.

Figure 2, a plairof the same.

Figure 3 shows the shape into whch the sheet metal is to, be out to form a. box for an oblong frame, as bere shown; a.nd

Figure 4 is a, plum of the box formed.

The frame o: cose A may be made of the size desired, ami o. piece of sbeet metal is then marked, and the corner ci1t.out, as shown in fig. 3, the central division being made to correspond to the inside length ami wid th of the frame and the wings,but to the exterior dotted lnes, With the dimensions of the sides ami ends respectively of the same.

' T0 form the sides a.nd ends of the box, the wings are beni: up et the interim dotted lines, a't righi? angles to the central -portion or bottone, and the top edges are berit outward al: righi: angles, ami thus is formed the complete box B, shown in fig. 4. As the vertical corners of 'the box B are not sol'dered, bui; loose or detaohed, it is slipped into the frame or c:ise A, in order that itmaj hold sofely th e liquid sirup. Its position in the frame is shown by dotted linee in fig. 2, the horizontl projeoting edges reoting on the frame, end preventing the box from s li ppn'g tbrough.

The bot'tom of the box should be supported free from contoct wth nny surface, anni a. free circulation of air allowed bencatb it, to bastn t-he cooling end hazdenng of the sirup. This may be efi'ected by gvng extra deptgh either tothe si'des or to tbe eds, or by blocks or supports attached to'tbe bottom of the sde or euds of tbe frame, as shown in fig. 1, or the frame itself may beplaced on tbe edges of strips or ruls provid'ed for that purpose.

As soon as the sirup has cooled a.n d beoome solirl sugzn, the frame may be turned over, and the box pusbed out, and tbe Ioose sides end ends cleaving off from the cake or block of sugar, it is at once s ot free, and ma be removed.

The frame A moy be made ,trianguhn, hexagonal, octagonal, or of any polygonal form desired, end 1:11e s'ides may be made oblique or flarng, and the tin musi; tben be out md bent so that the box formed of il: may jusb fit into the franie.

I claim a sheet-metal box B, having its vertical corners-loose or detached, in combination with a fram'e, A, 1'hto which it fits ami within which it is supported by its horizonfal e lges or flanges. substa.ntially as described, and for the purposes set fort JOHN S. INSKEEP. Witnesses:
